Can not change the range of dot size in GroupHeatmap functior/不能改变GroupHeatmap里的点大小范围

Sometimes 20% dot is too small, but there seems to be no way to adjust the minimum and maximum dot_size。
I have try to： trace(GroupHeatmap, edit = TRUE) ，line 419-422。However, it can only change the dot size of the legend, not the dot size of the graph

/有时候20%显示的点太小了，但是好像没法改点大小的最小值和最大值。我已经试过修改函数line 419-422，但是只能改图例上的，不能改图上的
